Or even simpler, put a cheap analog thermometer which records the min and max temperature in your fridge. Maybe not exactly this one, but something like that:

  I bought a digital thermometer with min/max from Walmart for $5, but the problem was the temperature would rise quite a bit (above 40F) if the door was left open even for ~10-30 seconds, so it was hard to use the "max" temperature reading. It would have been more handy if the thermometer's min and max responded more slowly to reject these short fluctuations.

    You could put it in something with substantial thermal mass as a buffer.
